First she started sweating, then she started moaning and then she started shaking. We thought it was a seizure, but it was just a treadlegasm. THERE SHE GOES AGAIN!!!
A euphemism is a term or a phrase used by individuals to refer to a controversial topic as overwhelmingly inoffensive as possible, as opposed to being politically incorrect (aka "enthusiastically offensive").
Unfortunately, the overuse of a euphemism will eventually devolve its meaning to the extent that itself becomes politically incorrect and will have to be replaced with another euphemism. This is a sociolinguistic phenomenon to as the "euphemism treadmill".
The term "mental retardation" was once a euphemism and politically correct term used to describe stupidity. The previous term was imbecile which was an actual medical category which comprised of idiots (IQ 0 to 25), imbeciles (IQ 26 to 50), and morons (IQ 51 to 70).
Over time, mental retardation and its associated verb "retard" became as corrupted as "imbecile" and "idiot" and was eventually replaced with "intellectual disability". It is now only a matter of time when being "disabled" is offensive and once again, slides down the euphemism treadmill.
A person (usually a girl around the ages of 12-19) who says they're bisexual just for the attention, making bisexuality a trend. They usually spam forums trying to cyber with someone, "I'm bi and proud of it' is usually what's in their signature.
Girls who think it's cool and edgy to be bisexual but don't date women. Or really fall in love with them. Just do it to turn thier boyfriend on or to be "experimental" or "open"
"She's a trendy Bi chick. You might be able to kiss her at a party, linda but she's not gonna go on a date with you."
